Fuel Sending Unit what lines go....?

[lennyKatan]

there are two lines coming out of the sending unit

at the side of the fuel tank.

One line should be the fuel out to the filter the other is a return line. My problem is I forgot which is which.

 

Also the two vent lines go to what?

 

I'm off my back and getting around so trying to finish

and getting my 89 comanche moving.

Well I'm on my back on the cold ground trying to get

my truck moving!

Once i get it started I sure I will fine what ---k up :fs1:

the largest one is for the output line, the smaller line is for the return line.

 

trail the lines, the one which goes to the fuel pump is going to the larger fitting.

Thanks for your reply.

I was thinking that was it while look up at it.

Just wanted to be sure.

What about the vent lines where do they go?

 

thanks for your help

The vent lines are supposed to go to a t-fitting with a single line coming off, which then connects to a steel line (looks like a brake line) which in turn goes to the charcoal cannister.
